Description

  The present invention relates to a horizontal positioning tool for a stepped portion. Specifically, the present invention relates to a horizontal positioning tool for positioning in a plan view on a surface where there are upper and lower steps.

  As a part of the foundation work of the building, there is a process of positioning the column bases and the direction of the underground beam. For example, when abandoned concrete is cast in a pit for foundation construction, a step is provided between the installation site of the underground beam and the column base installation site. This is because the surface on which the foot portion of the column base is generally installed is lower than the surface on which the underground beam is installed. In this case, the center position of the column base is usually set on the extension of the center line of the underground beam. For such foundation work, a method disclosed in Japanese Patent Laid-Open No. 9-78595 is known.

  However, since the step is formed on the surface of the discarded concrete, the positioning of the footing part is not easy. Conventionally, a construction worker manually attaches a lower swing to the tip of the rod, adjusts the position of the rod along the center line of the underground beam, and marks the position of the lower swing. Positioning is performed by. Thus, the manual preparation work is troublesome. In addition, since the downward swing is swayed by the wind or the like, it may take a considerable time to stop. In addition, it is necessary to adjust the length of the swing swing according to the height of the step.

Japanese Unexamined Patent Publication No. 9-78595

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a horizontal positioning tool for a step portion that is easy to carry and handle and can be quickly positioned.

  A horizontal positioning tool for a step portion according to the present invention includes a main body and a long vertical indicator member rotatably attached to the main body in a direction parallel to a direction perpendicular to the main body. The main body is formed with at least one of a scale shown along the longitudinal direction and an attachment for attaching the scale band along the longitudinal direction.

  According to such a configuration, the main body is held in a horizontal state on an upper portion of a flat surface with a step, and the vertical indicator member is simply oriented in a direction perpendicular to the main body, so that the lower indicator portion of the surface is A predetermined position is indicated. Next, if marking such as inking is applied to the instructed portion, desired positioning is performed. By such a simple operation, horizontal positioning at the stepped portion is performed. Moreover, since the main body and the vertical indicating member are integrated, it is easy to carry and handle. The scales shown along the longitudinal direction include both those in which a scale is formed directly on the main body and those in which a scale band is attached.

  In this horizontal positioning tool, it is preferable that the vertical indicating member is an elongated plate-shaped vertical indicating plate, and a level device for detecting the level in the longitudinal direction of the main body is attached to the vertical indicating plate. . This is because it becomes easy to make the posture of the vertical indicator plate vertical, and the positioning accuracy is improved.

  The vertical indicator member may include a cylindrical hood and a swinging swing attached to the hood or the main body so as to be able to hang down in the hood.

  The hood may be formed from a plurality of nested tubular bodies, and the length of the downward swing may be configured to change according to the length of the hood that expands and contracts.

  It is preferable that a level for detecting the level of the longitudinal direction is attached to the main body. This is because the posture of the main body can be easily leveled, and the positioning accuracy is improved.

  According to the horizontal positioning tool of the present invention, horizontal positioning work, carrying and handling at the stepped portion are easy.

  Hereinafter, the present invention will be described in detail based on embodiments with appropriate reference to the drawings.

  The horizontal positioning tool 1 shown in FIG. 1 has a long main body 2, a hood 3, a swinging swing 4, and a scale band (for example, a tape measure) 5. One end of the hood 3 is rotatably attached to one end of the main body 2. The downward swing 4 is an aspect of a vertical indicating member that includes a string 4a and a weight 4b attached to the tip of the string 4a. The downward swing 4 is attached in the hood 3 so as to pass through the hood 3. The hood 3 suppresses the influence of the wind on the downward swing 4. The scale band 5 is attached to the main body 2 along the longitudinal direction thereof.

  The main body 2 has a rectangular tube shape with a rectangular cross section. In addition to the rectangular tube, a channel material having a U-shaped cross section or a channel material having an L-shaped cross section may be used. As for the material of the main body 2, the bottom plate 2a and the left and right side plates 2b are selected from lightweight metals such as aluminum alloys, synthetic resins, and the like. The top plate 2c is made of a transparent resin such as acrylic. The scale band 5 is attached to the bottom surface of the main body 2. The user can read the scale through the transparent top plate 2c. Instead of sticking the scale band 5, the scale may be directly carved on the main body 2. Or you may comprise a scale band (for example, tape measure) in the main body 2 so that attachment or detachment is possible. In this case, for example, a locking pin for locking a locking ring at the end of the so-called tape measure is erected on one end of the main body 2. Or you may provide the fixing screw 20 for pressing and fixing the edge part of the tape measure S, for example, as shown in FIG. In any of the above cases, as will be described later, the reference point of the scale can be the point where the downward swing 4 is suspended.

  As shown in FIG. 2, the hood 3 is configured to be extendable and contractable by combining two rectangular cylinders of an outer cylinder 3 a and an inner cylinder 3 b in a nested manner. In FIG. 2, the hood 3 is drawn larger than the downward swing 4 for easy understanding. In the present embodiment, the inner cylinder 3 b is rotatably attached to the main body 2 via the hinge member 6. The hood 3 is rotatable with respect to the main body 2 between an action position WP extending in a direction perpendicular to the main body 2 and a storage position SP extending in a direction overlapping in parallel with the main body 2 (FIG. 1). Inside the inner cylinder 3b, reversing bars 7U and 7L for reversing the string 4a are bridged between the inner side surfaces in the vicinity of the upper end and the vicinity of the lower end, respectively. The material of the hood 3 is selected from lightweight metals such as aluminum alloys, synthetic resins, and the like. In order to monitor the swing of the downward swing 4, it is preferably a transparent resin such as acrylic.

  As for the downward swing 4, the base end part of the string 4a is attached to the upper end of the outer cylinder 3a. The string 4a passes through the groove 8 formed in the inner surface of the outer cylinder 3a from the attachment portion M, and enters the inner cylinder 3b through the through hole 9 formed in the vicinity of the lower end of the inner cylinder 3b. The string 4a is hung on the lower reversing bar 7L from below, extends upward, and hung on the upper reversing bar 7U from above and extends downward. With this configuration, the position of the tip (lower end) of the weight 4b with respect to the outer cylinder 3a is constant regardless of the expansion and contraction of the hood 3. That is, when the outer cylinder 3a is lowered by the dimension A (FIG. 2 (b)) from the state where the hood 3 is contracted (FIG. 2 (a)), the string 4a moves to the weight 4b side by the same dimension A. The weight 4b is lowered by the dimension A. The tip position of the weight 4b is always set at a position slightly above the lower end of the outer cylinder 3a.

  At least one side wall in the vicinity of the lower end of the hood 3 is cut off to form an opening 10 for inking (FIG. 1). The vertical dimension of the opening 10 may be substantially the same as or shorter than the vertical dimension of the weight 4b. This opening 10 is necessary when the worker inscribes from the outside to the position on the lower-stage discarded concrete LC indicated by the weight 4b.

  The attachment mode of the downward swing 4 is not limited to the above. For example, a reel (so-called small tool balancer) having a winding biasing mechanism such as a mainspring and a lock mechanism that locks the string 4a at an arbitrary pulling position may be attached in the hood 3 or the main body 2. (Not shown). The string 4a of the swinging swing 4 is wound around the reel, and the user can pull the weight 4b and pull out the string 4a by a necessary length for use.

  As shown in FIG. 1, a level 12 is attached to the main body 2. The level 12 is attached so as to detect the level in the longitudinal direction of the main body 2. By holding the main body 2 horizontally, the horizontal distance from the reference position on the upper-stage discarded concrete UC to the tip position of the weight 4b on the lower-stage discarded concrete LC can be determined more accurately.

  The horizontal positioning tool provided with the level 12 may have a laser beam transmitter (not shown) together with or in place of the swinging swing 4. This laser beam transmitter is attached so as to transmit a laser beam in a direction perpendicular to the longitudinal direction of the main body 2. By holding the main body 2 horizontally, the horizontal distance from the reference position on the upper discarded concrete UC to the position on the lower discarded concrete LC irradiated by the laser beam transmitter can be accurately determined. The on / off switch of the laser beam transmitter is attached to a position where the operation in the main body 2 is easy. When the laser beam transmitter is used instead of the swinging swing 4, the windproof hood 3 does not need to be installed. However, the main body 2 may be installed as a support for stabilizing the main body 2 in a horizontal state by grounding the hood 3 on the lower-stage concrete surface LC.

  FIG. 3 shows another horizontal positioning tool 11. 3A is a front view of the horizontal positioning tool 11, FIG. 3B is a plan view, and FIG. 3C is a left side view. In this horizontal positioning tool 11, a hood 13 is attached by a connecting metal fitting 14 so as to be slidable in the longitudinal direction with respect to the main body 2 and to be able to change the angle formed with the main body 2. . The hood 13 is not extendable. A scale may be formed on the hood 13. This is because it is possible to check the step size of the discarded concrete. The upper end of the string 4 a of the swing swing 4 is attached to the upper end of the hood 13. The length of the string 4 a is set so that the tip position of the weight 4 b is slightly above the lower end of the hood 13. An opening 10 for inking is also formed near the lower end of the hood 13.

  The main body 2 has the same shape and structure as those in the horizontal positioning tool 1 of FIGS. However, the main body 2 is not attached with a scale band, and a locking pin 20 for locking the locking ring at the tip of the tape measure S protrudes from the end of the hood 13. .

  As shown in FIG. 4, in the connecting metal fitting 14, a pair of rectangular holding plates 15 a and 15 b are connected to each other by a rotating shaft 16 so as to be rotatable back to back. 4 (a) is a front view of the connection fitting 14, FIG. 4 (b) is a sectional view taken along line IVB-IVB in FIG. 4 (a), and FIG. 4 (c) is an IVC- line in FIG. 4 (b). It is IVC sectional view taken on the line. One holding plate 15a fixes the main body 2, and the other holding plate 15b holds the hood 13 slidably. Fixed claws 17 having an L-shaped cross section are provided upright on the opposing sides of the front surfaces of the holding plates 15a and 15b. The main body 2 and the hood 13 are fitted and fixed between the fixing claws 17 of the corresponding holding plates 15a and 15b. The holding plate 15b for the hood 13 is provided with a leaf spring 18 curved in an arc shape for pressing the hood 13 against the other fixing claw 17 inside at least one fixing claw 17 thereof. With this structure, the hood 13 is elastically held by the connection fitting 14 and can slide in the longitudinal direction. In the present embodiment, a leaf spring 18 is also provided on the holding plate 15 a for the main body 2. If comprised in this way, usability will improve. By reducing the height of the fixed claw 17, the one side plate 2b of the main body 2 and the one side plate of the hood 13 are configured to fit between the two fixed claws 17 of the corresponding holding plates 15a and 15b. May be.

  A detent mechanism 19 is formed between the holding plates 15a and 15b for temporarily fixing each other at an angle of rotation of 90 °. Specifically, the detent mechanism 19 includes engagement holes 19a formed at intervals of 90 ° on the circumference around the rotation axis 16 on the back surface of one holding plate 15a (15b) and the other holding plate. It is comprised from the engagement protrusion 19b formed on the said circumference in the back surface of board 15b (15a). The engagement protrusion 19b can be elastically engaged with each engagement hole 19b. The positions of the engagement holes 19a and the engagement protrusions 19b are set so that the main body 2 and the hood 13 are engaged at positions where the angles formed by each other are 90 ° and 0 ° (180 °).

  The main body 2 is attached with a level 12 for detecting the level in the longitudinal direction. A level 12 is also attached to the upper end of the hood 13 so as to detect the level in the longitudinal direction of the main body 2. The level 12 is attached to the hood 13 in order to detect and adjust the perpendicularity of the hood 13 with respect to the main body 2. This is to cause the hood 13 to exhibit a vertical instruction function instead of the downward swing 4. That is, the hood 13 itself is a vertical indicating member. Specifically, it is as follows. The main body 2 is held in a horizontal state on the upper-stage discarded concrete UC in a state where the hood 13 is made to go straight to the main body 2. At this time, if the level 12 at the upper end of the hood 13 does not indicate that it is in a horizontal state, the hood 13 is adjusted by rotating it slightly relative to the main body 2. The rotation for this adjustment can usually be sufficiently covered within the play of the detent mechanism. Then, the ink is drawn on the part on the lower-stage discarded concrete LC indicated by the front end edge or the rear end edge of the lower end of the hood 13. According to this configuration, the vertical instruction function can be selectively exerted on either the hood 13 or the downward swing 4. Of course, when the hood 13 exhibits the vertical instruction function, the downward swing 4 does not have to be provided.

  FIG. 5 shows still another horizontal positioning tool 21. 5A is a front view of the horizontal positioning tool 21, FIG. 5B is a plan view, and FIG. 5C is a left side view. The horizontal positioning tool 21 includes a long-plate-shaped vertical indicating plate 22 as a vertical indicating member in place of the hood 13 (FIG. 3) having a rectangular tube. The holding plate 24 for the vertical indicating plate of the connection fitting 23 is provided with a fixing claw having a size corresponding to the thickness of the vertical indicating plate 22. A level 12 is attached to the upper end of the vertical indicating plate 22 so as to detect the level in the longitudinal direction of the main body 2. This is because the perpendicularity of the vertical indicating plate 22 relative to the main body 2 is detected and adjusted. In the horizontal positioning tool 21, a fixing screw 25 is provided on the main body 2 for pressing and fixing the end of the tape measure S that is a scale band. Of course, instead of the fixing screw 25, a scale band may be attached, or a scale may be directly formed on the main body 2.

  Inking on the lower-stage discarded concrete LC is performed on the discarded portion indicated by the front end edge 22a, the rear end edge 22b, and the like at the lower end of the vertical indicator plate 22. The scale of the tape measure S is convenient to use the position of the front end edge 22a or the position of the rear end edge 22b of the vertical indicator plate 22 as a reference as a reference (0). A scale 26 may be formed on the vertical indicator plate 22. For the horizontal positioning tool 21 having such a configuration, a downward swing 4 may be attached to the main body 2 as necessary. In this case, the downward swing 4 may be housed and attached to a reel (so-called small tool balancer) 27 having a winding biasing mechanism and a lock mechanism.

  The method for using the horizontal positioning tool described above will be described using the horizontal positioning tool 21 of FIG. 5 as a representative. First, a reference position is marked on the center line of the underground beam shown on the upper stage concrete LC based on the construction drawing. This reference position is a position where the distance to the center position of the column base can be covered by the scale of the main body 2. Next, the main body 2 is placed along the center line of the underground beam. Next, by moving the main body 2 along the center line, the scale of the tape measure S corresponding to the distance from the reference position obtained from the construction drawing to the center position of the column base is matched with the reference position. If it carries out like this, the discard site | part which the front end edge 22a of the lower end of the said vertical indicator plate 22 or the rear end edge 22b etc. will point will be a position corresponded to the center of a column base. Ink out at this position.

  According to the positioning tool described above, horizontal positioning work, carrying and handling at the stepped portion are easy. Therefore, it is useful for positioning the column base in the foundation work of the building.
